The present invention relates` to batchers ksuch as are employedfordischarging predetermined batches or amounts of sand, gravel or similarmaterial, and the inventiony aims toprovide a novel and improved deviceofthat kind. e i Y Another obj-ect of the invention is the profl visionof a batcher which maybe applied to the side wall of a silo or othercontainer for sand, gravel or similar materiahtoenable measuredquantities ofthe material to be delivered. Y

The invention has among its other objects to provide a batcher having anovelzad]ust able measuring chamber, novel means for controlling theflow and discharge of f the material, and novel operating means there-With the foregoing and other` objects in view, which will be apparent asthe descrip tion proceeds, the invention resides in the construction andarrangement of parts as hereinafter described and claimed, it beingunderstood that changes can be made within the scope of what is claimed,without depart-v ing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein-Figure 1 is a vertical 'median section ofV the improved batcher, takenon the line' 1-1 of Fig. 2.

Fig; 2 is a plan view looking in the direction of the arrow 2 inFigj 1,portions vbeing broken away and shown in section.

Fig. 4 isa sectional detail of the operative connection between the rockshafts connecting the gates. i-

Fig. 5 is an elevation of the cam segment shown in Fig. 4.

The batcher has an inclined spout 1 eX- tending outwardly and downwardlyfrom a substantially vertical plate 2 that is part of' 3, which issecured to the wall of a silo, bin or other; container for holding sand,gravel or similar material, in orderthat the materialfmay. flowVdownwardly and outwardly through thespoutlintothe batcher.,V .Y

i The batcher has a measuring chamber comprising thebottom 4 and sides5. The bottom 4 is inclined, and the spout 1 enters the upper end.portion of the measuring chamber. The side Walls 5 have a lower` endwall 6- between them, andthe lower end por-k tions of the bottom 4 andwalls 5 and 6 are formed with ahopper-shaped discharge portion 7y havingthe opening or outlet .Stol deliver the material into a truck or otherre'- ceiver.

The top of the measuring chamber includesy a fixed upper plate 9 towhichpartitions 10 are connected, said partitionsconvergmg up- Wardlyfrom the side walls 5 and having the portions 11 at the opposite sidesof they spout 1. The plate 9 has'an outturned flange 12 at its'upperedge adjacent to but spaced from the lower edge of the top of thespout1, as..

seen in Fig. 1.

A-cut-off-gate 134 moves across the lower end of the spout 1 to cut offthe flow of material through the spoutinto the measuring chamber. Thisgate comprises the side plates/or segments 14 anda curved yplate 15secured thereon` andfcurved about the axis ofthe shafts or rodsy 16'onwhich the side plates 14 are mounted fonturning movement. Said rodslare supportedby the side walls 5`of the measuring chamber and thesidewalls of the spout'l. In order to oscillate the gate 13, a gear seg-`ment 17 is mounted on oneofthe rods 16 and is secured to one side of thegate 13, asseen inr Fig.' 4, and the segment 17 meshes with a pinion 18ona transverse shaft 19 Ajournaled on the frame 3. A sprocketwheelQOissecured on one end if the shaft 19l Vand a chain 21 assesaround said sprocket wheel in order .conveniently pulled at thatthechain may be for either opening or a point lower down, closing thegate 17. l

Thelower end of the spout at22, around'the axis of rotation .of

l1 is rounded, as the gate V"13, so thatsaid gate'may move close to theendof thespout.l There is a dead space below the spout into whichthelower edgeof the plate 15 moves,

Vwhen the-gateV 13 is closed, thereby'permitting the gate to 4closewithout beingobstructed.

The lower edge of the gate may thus move through the material and underthe spout 1 without clogging. rllhe plate of the gate moves between thetop of the spout and the 5 plate 9.

The measuring chamber has an adjustable lower endwall 23 movable betweenthe side walls 5 on the bottom 4, and a lower top plate 24 is secured tothe end wall 23. The end wall 23 has wings 25 slidable along the sidewalls 5 and connected by a brace or strut 25a, and oblique portions 26extend between the wings 25 and end wall 23 and correspond the sideWalls of the hopper portion 7 to permit the end wall23 to be adjusteddownwardly to the limit. The end wall 23 may thus be moved down into thehopper portion 7, andk when moved upwardly to reduce the size of themeasuring chamber, the wings 25 and web portions 26 prevent leakage ofthe materialr between the walls 23 and 5.

The top plate 24 has downturned portions 27 at the outer sides of thewalls 5 and carries roller carriages 28 movable alongfoutstandingflanges or rails 29 secured to the walls 5, thereby mounting the plate24 and end wall 23 for free movement.

An intermediate top plfate 30 is disposed' in overlapping relation withlthe top platesl 9 and 24, as seen in Fig. 1, and has downturnedportionsv31 at the outer sides of the walls' 5 and carries rollercarriages 32 movable along` the outstanding iangesl or rails 313 securedtol the side walls 5.

are` located betweenY the walls 5 and portions 27 above the rails 29, asseen in Fig. 3, to avoidl interference between the mountings of theplates 24 andlv 30.

wal-1s 5 for the'contact of the lower ends of the portions 31, as seenin Fig. 1, to limit the downward movement of the plate 301 The pla-te3'0 closes the space between the plates 9 andv 24, andy when thel wall23 is moved upwardly it will contact with the plate 30 and move the'plate 30 upwardly with the w'all y23 over the pl`ate9". When the plate24 andv end will move downwardly with them, untilit is stopped bythe-stops 34'.

The measuring chamber thus has an ezi-A tensible top composed of theplates 9, 24 and 30:.

d The end wall is adjusted by means ofV The portions 31, carriages 32and rails 33 Outstanding stops 34 are carried byv the Wall 23 are moveddownwardly` the plate 30:

wall 23 to swing to and 'from the opening 38.

The gate 39 vhas an outstanding arm 41 on which a weight 42 isscrew-threaded or otherwise adjustably mounted, so that the weight willswing the gate 39 downwardly and upwardly against the wall 23 across theopening 33.

In order'te control the gate 39 toggle links 43 are pivotally connectedwith the gate 39 and with toggle links that are pivoted to brackets 45carried by the end wall 23, and the links 44 are connected by a yoke 46so that the two pairs of toggle links operate simultaneously. The links43, 44 break upwardly when the gate 39 swings open, as seen in dottedlines in Fig. 1, and move downwardly toward a straightened-ont positionwhen the gate 39 is closed, as seen in full lines in Fig. 1.

A link 47 connects one of the toggle links 44 with an arm 43 on asleeve49 that is feathered or splined on a rock sha-it 50 which has itslower end journaled in a: bearing 51 carried by the wall 6 and which hasits upper end journ'aled in a bearing 52 mounted on the frame 3 near thespout 1. The sleeve 49 is slidable on the shaft 50 when the wall 23 isadjusted, and the rocking movement of the shaft 50 will swin-g the gate39 open and closed.

Themovement of the cut-'eti' and discharge gatesV is synchronized sothat they open and close alternately. F or this purpose a sleeve 53? issecured on the shaft 59 adjacentto the bearing 52 and' carries a roller54 working in` al groove 55 in a cam segment 5G that is secured betweenthe gear segment 17 and corresponding -side plate 15 of the gate 13,seen in Fig. 4. The groove 55 has an oblique portion 57 near one end toswing'the' sleeve 53 and turn the shaft 50'. rlfhus, when the cu*- o'l'gate 13 is being closed and approaches its closed position the portion57 of 'the groove 55 engaging thev roller 54 will turn the' shaft 50 soas to raise the armr 43, and thereby through the toggle links 43, 44open' the discharge gate 39. Conversely, when the cut-cti gatestarts toopen'.y the oblique portion 57 ol the groove 55 will turn the sleeve 53and' shaft 5() to swing the gate 39 closed before the gate 13 has openedsuliiciently to permit the material to iiow into the' measuring`chamber. The discharge' gate is-tbns opened' during` the hnal closingmovement of' the cutoff gate, and'. is Closed duringl the initialopening movement of the cut-oli gate.

The opeiiation ci the batcher is simple, and will no doubt beu l- -stoodfrom the 'foregoing, but bri'eiiy described as tcllews: The

end wall 23 isradju'sted' so that the measuring chamber is' of a desiredcap: discharge a predetermined batch or Quantity of mate "ali When thecut-oit Igate 13 is opened, discharge gate 39 visclosed during theinitial opening movement thereof, and' Iity in order te the materialwill flow through the spout 1 intothe measuringchamber. Then, by closingthe cut-olf gate 13, the discharge gate is opened during the finalmovement of the gate 13, thereby permitting the material to dischargefrom the measuring chamber through the hopper portion 7 and outlet 8.

The cut-off gate 13 does not have a tight fit with the spout 1, but tothe contrary there is a clearance between said spout and'gate, to permitthe gate to move freely. When the gate is closed it provides a pocketunder the spout 1 to receive the material and to prevent same frompassing down into the measuring chamber until the VITate 13 is againopened. The gate 13 may thus swing open and closed freely, and will notbe clogged by pebbles, gravel, or the like.
